WHIFFLETREE.

Specification of Letters Patent.

Patented J an. 3, 1911.

Application filed July 14, 1910. Serial No. 572,052.

T 0 all whom it may concern:

Be it known that I, WALTER M. Brno, a citizen of the United States,residing at Mount Gilead, in the county of Montgomery, State of NorthCarolina, have invented a new and useful Improvement in Whiffietrees, ofwhich the following is a specification.

Figure 1, in the appended drawings is a perspective view of theinvention. Fig. 2, is a transverse or cross sectional view showing inpart the construction of the several parts, the manner of assemblingthem together and securing them in place. Fig. 3, is a View in detailshowing the elliptical form of the whiflietree and the niches orrecesses in the same. Fig. 4, shows the construction of both clips,clevises, bolts and nuts.

Similar letters of reference in the four figures indicate similar parts.

The object of my invention is to provide a whitlietree of sufficientstrength and low cost of construction, with interchangeable parts, allof which, or, either of which, may be replaced when broken or worn inuse, and to quickly, conveniently and successfully take up any slack orlooseness in both clips, clevises, bolts and nuts, which may fromshrinkage or other cause occur while in use, thus supplying a long feltwant on the part of those who use farm implements.

The body of the whiifletree, G, is constructed of any suitable materialof proper size and length, and is elliptical in shape and near each endon one edge are out vertical semi-circular niches or recesses, A, A, onthe opposite edge at the longitudinal center of the tree is cut a largerniche or recess, A to receive a bolt larger in size than those at theends of the tree. In these niches or recesses are embedded the bolts, G,C, C, when in position. The clips, E, E, E, are made of band iron orsteel, with a square perforation, B, at one end and a round perforation,B at the other, as in Rig. 4. The clevises, B, B, B, are made of iron orsteel rods and have near their ends square and round perforations B, andB corresponding with like perforations in clips, E, E, E. Both clips andclevises are without recesses. The bolts, C, C, C, are square adjacentto their heads the remainder being round and threaded to receive thenuts, D, D, D.

A whilfletree (or swingletree) embodying this combination inconstruction, to wit, with clips E, E, E, and clevises B, B, B, on thetree G, with the square and round perforations in each corresponding andin line with niches or recesses A A and A with bolts 0, C, C,penetrating perforations B, embedding. in niches or recesses A, A, and Aprotruding through B sufficiently to receive nuts D, D, D, the squareportion of bolts 0, C, G, engaging the square perforations B, isentirely ri 'id when tension of nuts D, D, D, is applie and by which anyslack or looseness, which may from any cause occur, can be easily andquickly taken up, thus constantly maintaining a close, firm, unyieldingcontact of clips E, E, E, and clevises B, B, B, with the tree G. Ifshrinkage should occur from exposure to the extremes of weather a littlemore tension on the nuts, D, D, D, will renew the original contact andrigidity of all the parts inasmuch as the square portion of the bolts 0,C, C, engage the square perforations, B, in both clips and clevises. A

Having thus described my inventiomwhat I claim and what I desire tosecure by Letters Patent is;

The combination of an elli tically formed tree G, niched or recessed A,A with clips E, E, E, and clevises B, B, B, with perforations B, and Bwith bolts C, C, C, the square portion of which engages the squareperforations B, embedding in the niches A, A, and A penetratingperforations B with nuts D, D, D, on their protruding ends in the mannerand for the purpose set forth.
